Crew Progression/Hidden Skills

Besides their regular, listed skills (called "primary" here), all crew members are more or less proficient in all other, hidden/unlisted skills (="secondary") as well, although these values are considerably lower than their primary skills.

The secondary skills of any crew member are determined according to the following rules:
 * The secondary skill is determined by the worst primary skill of the character.
 * The value is exactly 20% of that skill. The base/main value is rounded correctly to the nearest value, while the low/high RNG values are rounded down to the next value. For example, if the worst skill is 99 +(99–99), all secondary skills would be 20 +(19–19).
 * These values are the same for all unlisted skills of the character, and are not influenced by items that would give a bonus in such a skill.
 * The "worst primary skill" is determined by the maximum achievable value of all skills. For example, and  result in maximum possible values of 30 for  and 29 for . Therefore,  is considered worst, although its base, min, and average values are all better than  (see example of Mirror Ezri Tigan below).

As this info can be exploited and/or might be useful mastering certain missions (as with A Tale of Forgotten Lore in the past ), it might be integrated at some point into the crew member pages.

Skill Table
In the following table, crew members may/must be listed more than once, as the skill level depends on the XP level, and possibly also the fusion level.

NOTE: As the rules for the secondary skill are now fully discovered, there is no need to extend or update this table anymore.
